Taking omega-3 fish oils could help to protect against skin cancer, according to researchers at The University of Manchester. The team has just carried out the first clinical trial to examine the impact of the fish oils on the skin immunity of volunteers. Led by Professor Lesley Rhodes, Professor of Experimental Dermatology from the Photobiology Unit Dermatology Centre at the University, the study analysed the effect of taking omega-3 on 79 healthy volunteers.
